On Faulting in Nanocrystallites of FCC Metals

摘要

Patterns calculated by applying the Debye function to faulted spherical nanoparticles are used to test the accuracy of modern Line Profile Analysis theory of faulting for small crystallites.The relative deviation of the determined fault density is found to be dependent on the fault position, and on the particle size.The study of the average pattern from systems of 100 particles (D = 9.8nm) shows an overestimated deviation of the determined fault density by as much as 30%.
